On average, the Moon's surface temperature is 107°C (224.6°F) during the day
and -153°C (-244.6°F) at night -- this is why the moon is much brighter
in IR than Earth.

The hottest temperature recorded on Earth was 70.7°C (159°F) in the Lut Desert in Iran; the temperature was recorded by a NASA satellite. The coldest temperature recorded on Earth – which was measured by the Russian Vostok Station – was -89.2°C (-129°F) on July 21, 1983 in Antarctica.(read more)
